Learning a second language and speaking it regularly can improve your cognitive skills and delay the onset of dementia, according to researchers who compared bilingual individuals with people who spoke only one language.

Their study suggests that bilingual speakers hold Alzheimer's disease at bay for an extra four years on average compared with monoglots. School-level language skills that you use on holiday may even improve brain function to some extent.

In addition, bilingual children who use their second language regularly are better at prioritising tasks and multitasking compared with monolingual children, said Ellen Bialystok, a psychologist at York University in Toronto.

"Being bilingual has certain cognitive benefits and boosts the performance of the brain, especially one of the most important areas known as the executive control system," said Bialystok on Friday at the annual meeting of the American Association for the Advancement of Science in Washington, DC.

"We know that this system deteriorates with age but we have found that at every stage of life it functions better in bilinguals. They perform at a higher level. It won't stop them getting Alzheimer's disease, but they can cope with the disease for longer."

She said switching between different languages seems to stimulate the brain so that it builds up a cognitive reserve. "It is rather like a reserve tank in a car. When you run out of fuel, you can keep going for longer because there is a bit more in the safety tank."

A.The effect was greatest for people who had to use the language every day and choose between two sets of words all the time.B. "It works best for people who speak two languages every day, like immigrants moving to a new country who speak their own language at home. C. But every little bit helps." D.

Bialystock said her team was now researching whether using two or more languages resulted in any physical changes to the brain, in addition to improving cognition. Early results suggest that it may change brain size.

Do you agree or disagree with the following statement? Television
has destroyed communication among friends and family. Use

specific reasons and examples to support your opinion.

Спершу, сформулюй свою думку:

One may say that television has destroyed communication among friends and family. I think that television has remarkably changed communication between friends and relatives. Whether it's a black box or a flat screen, once installed in your home it influences people around, their lives, their thoughts and therefore their communication. More importantly those changes follow them to their jobs or schools, or anywhere they go.

Далі, поясни, чому ти так думаєш, надавши пару прикладів:

To begin with, television takes our time. So we may assume that there is less time left for communication. Then, our communication during that shortened period of time is greatly influenced by what we have seen on television: evening news, celebrities, TV shows' main characters and their lives. We discuss movies and current events, we start comparing our lives to those shown to us on the screens.

Furthermore, those changes in communication shape TV programs. People tend to look for advice on a talk-show than asking their friends, we tend to look for a role-models on TV, rather than in our lives, from people we know. We become truly empathetic with heroes of reality shows trying not to miss a program, and neglecting beggars on the streets and missing calls of our friends.

Далі, можна додати contrast своїм думкам:

On the other hand, there are lonely people who have none to talk to, no relative and no friends. Due to their personal loss or physical disabilities, they are obliged to stay at home, and TV may allow them at least visually experience the world, learn something new about a different culture, or follow the news on ongoing events from the country they were forced to leave. For those people television is a means to stay in touch with the world and to communicate with it. And from this angle, television creates a new and maybe only way to communicate.
